In order to improve the aseismic performance of a new multi-layer frame-bent industrialbuilding structure,the linking device for energy dissipation and earthquake mitigation is designed,and the structure dynamic behavior and the response under the earthquake are studied. Based on thedissipation characteristics of the device,structural natural vibration periods and vibration models arecomputed using the ANSYS saftware,and the elastic-plastic responses of the multi-layer frame-bentindustrial building structure are analysed through the input of three seismic waves under the action ofrarely occurring 7 degree earthquake. The results show that,compared with those of the structureswith welding embeded steel pieces,the averages of the maximum transversal displacement decrease51.9%,19. 3% and 23. 1% respectively,and the averages of the maximum shearing force decrease59. 0%,71. 6%,75. 9% respectively for the first,second and third storey of the structure with thelinking device for energy dissipation and earthquake mitigation.
